SPECIFICATION forming part of Letters Patent No. 386,181, dated July 17,1888.

(No model.)

To aZZ whom, it may concern:

Be it known that I, Maltees E. BLINN, a citizen of the United States,residing at Belle Plain, in the county of Cumberland and State of NewJersey, have invented certain new and useful Improvements inLamp-Extinguishers; and Ido declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertaius to make and use the same,reference being had to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form a part of thisspecification.

My invention relates to certain newand useful improvements inlamp-cxtinguishers, and it consists in a lamp having a movableilamecover connected by mechanism to a iloat within the body of thelamp, whereby the flame-cover is moved by the rise and fall of thefloat.

The object of my invention is to extinguish the dame of a lampautomatically at any given time by mechanism connected with the lamp. Iattain this object by means of the peculiar construction and arrangementof the various parts of my inventiomwhich will be more fully described,and set forth in the specification and claim, reference being had to thedrawings accompanying this application and forming part of the same, inwhich- Figure l is atop plan view of my invention. Fig. 2 is a verticalcross-section on the line yy of Fig. 1. Fig. 3 is a verticalcross-section taken on the line x .c of Fig. 2. Figs. L1,5,and 6 aredetail views.

Similar letters refer to like parts throughout the drawings.

Referring to the drawings, A represents a lamp, which has a removablecover, B, and the center of the lamp A is provided with a verticalcylinder, G, adapted to receive the lamp-wick and form a guide for theiloat D, which is formed of any suitable material and provided with acentral perforation, E, adapted to loosely fit around the cylinder C.Said oat D, being made ,hollow or of buoyant material, iioats on top ofthe oil within lamp A, and at one side it has a vertical rod,F,projecting from its upper face,thatextcnds up through a perforation, a,formed in the cover B. A plate, Z), having upwardly-projecting arms c cc c', and a perforation, d, is secured to the upper face of cover B bysoldering or otherwise,

and placed so that the perforations a (Z, respectively, in the plateband coverB register, and through which the vertical rod F passes. Oneofthe projecting arms, c', is marked with lines c'L across its outerface and numbered, thus forming a scale, c, as shown in Fig. 4.

rlhe central portion of the cover B is provided/with a centralperforation, c, over which is secured an open ring-cap, j', to receivet'ne burner g and the lampwick in the usual form.

A bracket, h, having end projections, z', and clamp-arms j, is securedto one side of the outer end of the wick-tube g by means ot' said arms jbeing bent around and clamping said wick-tube. An inclined hood, Zt, isformed of metal and bent at right angles to form projections Z Z', saidprojections having perforations m on, into which are inserted the endprojections, c', of bracket Zi, forming pivots on which said hood krotates.

One of the projections, Z, is formed with an extension, Z, into thelower edge of which is cut a slot, Z3, into which extends thebenthorizontal portion n of the vertical rod o, said rod extending downthrough the burner-base o', audits lower end is joined toa horizontalplate, p, the outer end of which is formed with a curved-lip hand-piece,p', and near the base of said lip p is formed a perforation adapted toiit the vertical rod F.

rlhe arm c', that is formed with cross-lines as a scale, has also formedon its inner face about midway itslengthashoulder projection, c, onwhich one edge of plate p rests when set to operate the hood k, as shownin Fig. 4, and by moving the arm c outward the plate D is released andfalls, and by means of the connecting-rod o moves the hood instantlyover the top of the wick and extinguisnes the flame.

A ring, q, having a projecting b1acl et,r,and a set-screw, s, is formedto tit over and ou the vertical rod F above the plate p, the purpose ofwhich is to set at the desired place on the rod F opposite the scale onarm c', so that the Iloat in its downward course by the evaporation ofthe oil in lamp A Will bring the end of the projecting bracket r incontact with the i11- ner l'acc of arm c and force it outward, releasingplate p, which immediately drops, causing the hood to extinguish theflame, as before stated, by means of the rod o, working in the slot Zt,rotating the hood Zt and curtain k' over IOO the end of the lamp-wick,said curtain being hinged to the front edge ofthe top ofsaid hood, andis brought directly in contact with the flame as the hood is rotated.

To aid in forcing the plate 19 downward is placed a spiral spring aroundrod F between the platep and the ring q, the ring q working against thetension of the spring t as the rod F descends.

The operation of my invention or device is as follows: Oil is placed inthe lamp A. The float D is kept at the surface of the oil, the verticalrod F projecting above the plate p. The coiled spring I is placed overrod F, its lower end resting on the plate p. The ring q is placed on rodF, and held by set-screw s at any point desired within the limit of thescale on arm c', the number on the scale indicating the number of hoursthe lamp A is required to burn before the plate 'p is pushed down by'coiled spring I. The plate p rests on the projection c2 of arm c, andas the oil in the lamp evaporates the rin g-bracket r comes in contactwith arm c', forcing it outward, thus releasing the plate p, when thecoiled spring t, together with the weight of plate p, causes said plateto descend and with the rod-connection o, pullsthe hood 7c over the endof the wick-tube, when the curtain k extinguishes the flame. Rod F isprovided with scale-marks to set ring g.

Having thus described my invention, whatI claim, and desire to secure byLetters Patent,

is- M In automatic lamp-extinguishers, the-float D, concentricallyencircling the wick-cylinder C, having a spindle or rod, F, rigidlyaffixed thereto, in combination with a plate, p, having arms c c', thelatter provided with a scale en circling the graduated rod F, the springt,1nain tained between said plate p andthe ring q, having a set-screw,s, the rod o, rigidly secured to the upper surface of the platep at oneend and terminating in a bent arm, n, at the other end,which oscillatesin the slot Z3 of the curved extension Z2 of the hood k, having abracketor back, h, and extinguishing-curtain k', pivotally suspended from thefront of said hood, whereby each' vertical movement of the ioat Dsynchronously effects a like motion of the rods F o, thus oscillatingthe hood kin the arc of a circle, for the purpose and in the mannerspecified.

In testimony whereof I affix my signature in presence of two witnesses.

MARCUS E. BLINN.
